Overload protection
To protect the motor, operator and diamond drill, the ma-
chine is provided with a mechanical, electronic and ther-
mal overload safety system. Whenever the engine is swit-
ched off due to overload, it must be switched on again as
soon as possible to cool the engine. Then let the drill turn
for a minimum of 1 minute.
1 - Electronic / Thermal
Whenever the engine is heavily overloaded , the overload
indication (LED) on top of the handle will start flashing. The
pressure on the diamond drill bit must than be reduced.
When the motor is overloaded too long, the LED flashes
continuously and the machine will switch off automatically.
2 - Mechanical
If the drill bit suddenly gets stuck, the slip coupling is acti-
vated to disconnect the main axis from the engine. Make
sure you switch off the engine immediately and remove the
drill from the hole. When the slip coupling is activated for
a longer periods, the mechanical slip must be re-tuned by
a recognised expert.
Drilling with water cooling - Water connection
IF APPLICABLE
The drilling machine is equipped with a water tap, which
includes a ‘Gardena’ connection. Make sure that the core
drill is sufficiently cooled and that the slurry is properly
discharged. The maximum permitted water pressure is 3
bars. Always use clean water to enlarge the life span of
the internal water seals. In case of leakage, the drilling
machine has to be checked IMMEDIATELY by a certified
mechanical expert.
Dry drilling - Dust Extraction
IF APPLICABLE
For dry drilling only use designated drill bits. Dry drilling is
only possible in masonry, brick/block and sandstone.
Dust released during dry drilling is dangerous to your he-
alth. Therefore a dust extraction system specially intended
for this purpose must be used, and if necessary, a dust
mask worn. The use of a dust extraction system is also
required to optimize the life time of the diamond drill bit. To
prevent clogging of the dust extraction system it is essenti-
al that the materials which are being drilled are completely
dry. Information about dust extraction systems is available
at your diamond tools supplier.
Dustec ® dust extraction
The A-1810DT is equipped with an integrated Dustec ®
dust extraction system which is only suitable for Dustec ®
drill bits (with dust holes in the top flange) of max. Ø82 mm
and M16 (F) connection.
The drill bit can be mounted directly on the output shaft. To
remove the drill bit fixate the output shaft with a spanner
24. Then loosen the drill bit with a spanner 24, through the
hose connection of the dust extraction.
The dust released during drilling is dangerous to your he-
alth. The A-1810DT is therefore only to be used in combi-
nation with a suitable vacuum cleaner, which is connected
to the hose connection on the Dustec®
system.
NASTROC ® system
The A-1821 is equipped with the robust NASTROC ® sy-
stem and the diamond drill can be changed without using
other tools. The lock nut has to loosened, so that the dia-
mond drill with NASTROC ® connection can be assem-
bled.
ENVIRONMENTAL PROTECTION
According to the European regulation 2012/19/
EU, CARAT is responsible to recycle old electric
drill motors. You are therefore requested to re-
turn old CARAT electric drill motors to your local
reseller.
